Be it known that I, CLARENCE Runnin- WICZ,

I the casing and attached thereto to receive inserted in one of the openings.

'is a perspective detail the ends of iron pipes diiits.

Referring to the drawing, Figure 1 is a perspective viewof a device embodying the invention with the cover detached; Fig. 2 showing the inner face of a wall of the box or casing; Fig. 3 is a perspective view of a socket member detached; Fig. 4. is a perspective view of a securin member; Fig. 5 is a perspective a modified construction; and Fig. 6 is a sectional detail of the construction shown in Fig. 5.

his device is especially adapted for work where the electrical conduits are inclosed within iron pipes, and forms a connection for inclosing the conwhe're the conduits meet and where branches formed of sheet metal with the metal of the sides, ends and bottom pressed outward at are taken off to support and hold the ends of the pipes and receive the ends of the conduits.

In the drawing 1 represents a rectangular box having sides 2, ends 3 and a bottom 4. The open top of the box is closed by a plate 5 secured to, the box in-any suitable manner as by screws passingthrough openings 6 in the plate and engaging similanopenings in suitable ears or projections 7 upon the sides of a box at their upper edges. -Each side, end and the bottom of the box or casing is provided with a circular opening 8 having. a plurality of laterally extending notches. 9 and a detachable socket member 10 having a reduced inner end 11 to fit within any one .or, the openings 8, is provided with a lurality of outwardly extending lugs 12 on its reduced end adapted to be passed through the notches 9 when thesocket member is a citizen of the. United States of America, residing at Detroit, in thecounty of the lugs and against the inner face 0 ing metal disks 20 may side of which will engage the side'wa These lugs plurality of the reduced end 11 and thus when said reducedend is inserted through one. of the openings 8 and the socket 'member then turned, said lugs will engage the inner face of the wallof the box and securely hold the socket member in place in the opening. To firmly hold the socket member from turning and becoming detached, a securing member 15 is provided which is shaped at its inner side to fit the curve of the reduced end 11 of the socket member and is of a length to just fit between two of the lugs 12. After the socket member has been inserted in one of thetopenings and turned, this securing member is placed between two I f the wall of the which'is inserted through a ho1e 16 in the wall and screwed into a corresponding hole 17 in the member 15.

The outer enlarged end 18 of the socket I member 10 may be internally screwthreaded or otherwise suitably formed to receive the end of an iron pi e which forms the casing for the electrica conduit which is le through the pipe and through the socket member into the. box or casing "1 where branches may be taken off and led throughthe other openings. One or more of the socket members may several openings not in use, vided.

In Figs. 5 and 6'the box is shown as 19 in a form corresponding to the openings 8 and their radial notches, the metal being drawn in such a manner that it 13 nearly lsevered along alineconformmg to the shape of the desired opening and thus the project- I be readily punched out'when it is desired to use one of the openings, saiddisks forming a box and made fast by a screw be used as desired and if found desirable, suitable closuresfor the may be proclosure integral;

with the box until so knocked out: To hold the socket members. from turning when inserted through the end walls, a triangular shaped member 21 may be provided,uomfa Q the box.- I-Iavin formed with/a circular opening laterally extending notches, a

having a.

thus fully described myinvention what I c aim is:-- a

pipe at its outer end and tubularsocket member adapted to receive a having a reduced inner end to fit said opening and forming a shoulder to engage the outer face of the wall, a series of outwardly extending lugs on the reduced end of the socket member spaced from said shoulder, and a member adapted to be secured on the inner side of the Wall of the box to'engage one of said lugs and prevent the turning of the socket member. v7

2. An outlet box comprising a Well have ing a circular opening therein formed With.

- opening,-said der to engage the outer side of the-Wall raradially extending notches, a socket member having an outer end adapted to receive a pipe and a reduced inner end to fit said reduced end forming a shouldially extending lugs on the reduced end of the soeketmember spaced from said shoulder and adapted to pass through the said notches and engage the inner face of the Wall When the socket member is turned, and a securing member adapted to be secured to the inner face of the Wall and of a'length to fit between two of the said lu s in en a ev p z: a:

3'. An outlet box comprising side andend wallsand a bottom each formed with a circular opening having radially extending notches, a tubular socket member .formed'at its outer 'end to at itslinn'er end to fit any-one of the said openings and to form a shoulder upon the socket member to enga e the outer face of the wall, radially exten duced end of the socketv member spaced from said shoulder, a securing 'mer nber curved at onelside to fit the curve of the rereceive a pipeand reduced ing lugs'on the re- 'l duced end of the-socket member and of a. 1

length to fit between means for securing said member toth e inner face of the wall in open top of the box to close the same. i In testimon whereof I afli'x' my signature in presence 0 two Witnesses.
